App Sandbox In Macos
- App Sandbox provides protection to system resources and user data by limiting your app’s access to resources requested through entitlements. To distribute a macOS app through the Mac App Store, you must enable the App Sandbox capability.
- The app is sandboxed. This means the application has been code signed with a set of entitlements. These entitlements are being enforced by Mac OS X. Apple's developer documentation on sandboxing provides more detail. You can view Xee's sandbox entitlements using the following Terminal.app.
- App Sandbox is an access control technology provided in OS X, enforced at the kernel level. Its strategy is twofold: App Sandbox enables you to describe how your app interacts with the system.
- I am working on an app for OS X 10.9 with swift, sandboxed. The app needs access to a SQLite database file. I let the user choose/open a file with NSOpenPanel. I then save the file path with NSUserDefaults for later use. I want this file to be opened automatically every time when the app is started again.
It isn’t widely advertised, but macOS ships with a standalone sandboxing utility out of the box: sandbox-exec. /how-to-reset-books-app-on-my-apple-mac.html. While the very short manpage says the utility has been marked deprecated, and for quite a few major releases now, it’s used heavily by internal systems so it’s unlikely go away anytime soon.
It’s best to interpret “temporary” in the context of the Mac App Store, where apps using these entitlements for their initial sandbox efforts were expected to move to some alternative approach as the App Sandbox improved. However, given that you’re not deploying via the Mac App Store, the “temporary” shouldn’t concern you. About App Sandbox. App Sandbox is an access control technology provided in macOS, enforced at the kernel level. It is designed to contain damage to the system and the user’s data if an app becomes compromised.
Sandbox configurations are writen in a subset of Scheme. A minimal useful starter example for wrapping a modern application might look something like this:
Saving the above as config.sb, you can use it to sandbox an app as follows:

To see all the operations that were denied, open Applications → Utilities → Console and search for sandbox and the application name. Historically, you could use the (trace 'output') command, but this seems dysfunctional on the latest macOS.

Most modern applications will not function with such limited permissions, so expect some back and forth before your sandbox profile works.
Depending on your OS version, you can find some system sandbox examples in some of the following locations: Best free journal app mac.

The tool has virtually no official documentation so some hacker insight can come very handy. There’s a number of useful examples here:

Setting up a Sandbox from scratch can often be largely trial and error — disallow everything, and then follow the trail of errors to see what you need to enable as a bare minimum to make the app work.
On the upside, it’s a great way to gain insight into what closed source binaries are trying to do on your system.
